How cold did the ice age really get?

Scientists revisit the question of global temperatures during the last ice age. They tackle this with state of the art climate models and geochemistry to give a picture that’s more accurate than ever before. Shawn WangI am a PhD student studying climate physics and marine geology at MIT and Woods Hole Oceanographic Institution. I am […]

Uneven Ocean Warming as the Planet Shed its Ice

Our oceans underwent major changes when the planet transitioned from the Last Glacial Maximum to our current interglacial (or “between glaciations”) period. So what was going on in the ocean during this transformation? Julia DohnerJulia is a PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is on biogeochemistry, which, as […]

Reconstructing climate history from sediments in the Gulf of Taranto, Italy

What was the climate like in Southern Italy 10,000 years ago? This question and many more can be answered by collecting sediment from the seafloor. Understanding the types of sediment and where it all came from, and determining the age of deposition make it possible to reconstruct the history of regional climate. Brian CaccioppoliI am […]

Catastrophic floods or drought? What caused the water level drop of glacial Lake Agassiz?

Formed from the meltwater of a colossal ice sheet that once blanketed North America, glacial Lake Agassiz experienced a sudden drop in water level approximately 12,900 years ago. The timing of this event aligns with a climatic return to cold conditions for 1,000 years, known as the Younger Dryas. A well-established hypothesis suggests that catastrophic […]
